The Influence of Human Activity on the Environment
The surge in human population in the last 2,000 years, due in large part to better health care, has brought a surge in the demand for resources and in pollution. The graphics, photographs, and real-life examples in a thought-provoking...
Curated OER
Eutrophication
Students observe the effects of eutrophication and determine why it is harmful to aquatic ecosystems. They create mason jar ecosystems to observe the growth of algae in pond water. In addition, they observe the effect of introducing...

"Dead-Zones" and Coastal Eutrophication: Case-Study of Chesapeake Bay
Take an in-depth look at nutrient loading, eutrophication, and hypoxia using data on The Chesapeake Bay as an example. This comprehensive presentation includes detailed graphs, photos, and details about the changes in marine organism...

AP: Chapter 54: Ecosystems
A lot of learning is packed into these 23 questions about ecosystems. Advanced biology classes apply their knowledge of communities, productivity, biogeochemical cycles, and human impact on the environment by writing short answers for...

Week 3: Pollution Source and Effects
Lab groups set up an experiment to observe what happens over time in collected pond water when fertilizer, representing pollution, is added. This website does not include student lab sheets, but background information, materials, and...
Curated OER
Plankton
Students explore how to collect plankton and use microscopes to observe and identify it. They collect the plankton sample and classify the various components of the plankton. Students identify organisms in the plankton and draw...

Measuring Exponential Growth
Middle schoolers reinforce math skills while learning about best practices
for protection of water quality in the management of animal feeding
operations. They make a table to show results of their calculations and compare and justify...
Curated OER
Eutrophication Lab
Middle schoolers examine the effects of detergents and fertilizers on aquatic life and describe algae. Students define the term eutrophication as the process by which a body of water, such as a pond, lake, stream, or river, has a sudden...
Curated OER
Pea Soup Ponds
Students perform an experiment where they learn how water can be polluted by algal bloom. They grow algae with different concentrations of fertilizers or nutrients and analyze their results.
Curated OER
The Nitrogen Cycle
Learners study the nitrogen cycle and construct a diagram. In this Earth Science lesson students use role play to see the various paths.
Curated OER
Biochemical Cycles: Recycling Carbon and Nitrogen
Students construct flow diagrams of the carbon and nitrogen cycle processes. They identify sequences in each cycle that are affected by human impact and present their research to the class.
Curated OER
"The Good, The Bad, and the Bountiful" Algal Blooms
In this biology worksheet, students draw 2 illustrations of the nearshore environment before and during algal blooms. They explain what happens after the bloom is over.
Curated OER
Ions in the Environment
Students explain the importance of the five main biogeochemical cycles. In this chemistry lesson, students discuss how ions are transported in the environment. They design an experiment to collect data on eutrophication.
Curated OER
Effects of organic material and nutrient pollution
Students create a definition of eutrophication. For this organic material lesson students work together to create a storyline.
